Today DILR question doubt

question 1 & 4 could be solved by analyzing graph and gap values
for q2 & 3 you would need to eliminate options but it gets kinda lengthy

It was more about having a clear visualization of the graph
You can think that this small amount ahead of 25 - "i will call it 30, a little more forward , i will call it 35 " in that sense , and stick to it ,throughout the question (be consistent with the value you assigned to that point) and you will solve all the questions , since they are not specific value based , but rather assumptions based
